Process Unit 73 LF Interface Bus Protocol Applies only if you have selected BUS coupling! The protocol is based on a master/slave relationship. The participants addressed by the master (host computer) are called slave. They have to execute the communication sequence as prescribed by the controlling master. Each communication sequence between participants on the bus is basically determined by two sections, the command section and the response section: In the command section the master defines meaning and function of the currently transferred message. The command information is accepted by the slave and correspondingly evaluated. The response section shows the master if a bus transfer has been properly executed. It can also contain data, if required. Data Format Hardware: RS485 2-wire. The data format is permanently set to 9600 bauds, 8 data bits, no parity. Each slave has a bus address that may be in the range 01...31. Each slave on a bus system must have a unique address. The address 00 is a broadcast address (message to ALL). Structure of a Message 1 Byte 1 Byte n Bytes 2 Bytes slave address status flags length: n + 2 ASCII message, as with point-to-point connection, but without message terminator CRC16 according to CCITT–X.25 12–30 Interface Commands
1st Field: Slave Address, Status Flags 7 6 5 4 3 2 1 0 ”1” master / slave error slave address 01...31, 00 = broadcast Bit 7: ”1” This bit must be set to logical One. Bit 6: Master / Slave: ”1” means that the message was sent from master to slave. The slave address addresses the data sink. ”0” means that the message is a response from slave to master. Here, the slave address indicates the data source. Bit 5: Error During transmission master→slave always ”1”. During response slave→master erased if an error has occurred. (e.g. syntax error; not for CRC error since in that case there won’t be a response). Slave address 00 has a special function: 00 addresses all slaves. No slave may send a response. Therefore, the master does not know if the message was completely understood by all participants. Nevertheless, this function can be useful for synchronizing all participants (e.g. to set clock). Afterwards, each participant can be individually checked if it has successfully received the respective message. 2nd Field: Length 7 6 5 4 3 2 1 0 ”0” more length of message field and CRC16 The length field indicates the remaining message length, i.e. length of message block and CRC (message + 2 bytes). In the case of correct reception, exact length bytes must follow after having read the length. Up to 63 bytes can be transmitted in each block (61 data bytes and 2 bytes CRC). Longer transmission strings must be divided into blocks. The ”more” bit is set if another complete data block follows. In a block sequence, the ”more” bit of the last block is erased. If the ”more” bit is erased (normal case), the message is complete with this block. 3rd Field: ASCII Message This message field contains the command to the Process Unit 73 LF. The message has the same structure as the string of the point-to-point connection (e.g. RV2). The message terminator is omitted. The message is immediately followed by CRC16. All characters in this field must have bit 7 erased (as 7 data bits, space parity). Interface Commands 12–31
